Part 1
1 System Configura ons
Heat pump can be configured to run with the electric heater either enabled or disabled and can also be used in conjunc on with an auxiliary heat source such as a boiler.
The chosen configura on affects the size of the heat pump that is required. Three typical configura ons are described below.
Configura on 1: Heat pump only § The heat pump covers the required capacity and no extra hea ng capacity is necessary. § Requires selec on of larger capacity heat pump and implies higher ini al investment. § Ideal for new construc on in projects where energy efficiency is paramount.
Configura on 2: Heat pump and backup electric heater § Heat pump covers the required capacity un l the ambient temperature drops below the point at which the heat pump is able to provide sufficient capacity. When the ambient temperature is below this equilibrium point, the backup electric heater supplies the required addi onal hea ng capacity. § Best balance between ini al investment and running costs, results in lowest lifecycle cost. § Ideal for new construc on.
Configura on 3: Heat pump with auxiliary heat source § Heat pump covers the required capacity un l the ambient temperature drops below the point at which the heat pump is able to provide sufficient capacity. When the ambient temperature is below this equilibrium point, depending on the system se ngs, either the auxiliary heat source supplies the required addi onal hea ng capacity or the heat pump does not run and the auxiliary heat source covers the required capacity. § Enables selec on of lower capacity heat pump. § Ideal for refurbishments and upgrades.

4.1 Selec on Procedure
Step 1: Total heat load calcula on Calculate total heat losses of the building. Select the heat emi ers (type, quan ty, water temperature and heat load).
Step 2: System configura on
Decide whether to include AHS and set AHS’s switching temperature. Decide whether backup electric heater is enabled or disabled.
Step 3: Selec on of outdoor units
Determine required total heat load on outdoor units. Set capacity safety factor. Select power supply.

Provisionally select heat pump unit capacity based on nominal capacity.

Correct capacity of the outdoor units for the following items: Outdoor air temperature / Outdoor humidity / Water outlet temperature¹ / Al tude / An -freeze fluid.

Is corrected heat pump unit capacity Required total heat load on outdoor units².

Yes

No

Heat pump system selec on is complete.

Select a larger model or enable backup electric heater opera on.

Notes: 1. If the required water temperatures of the heat emi ers are not all the same, the heat pump unit’s outlet water temperature se ng should be set at the highest of the heat emi er required water temperatures. If the water outlet design temperature falls between two temperatures listed in the outdoor unit’s capacity table, calculate corrected capacity by interpola on. 2. If the outdoor unit selec on is to be based on total hea ng load and total cooling load, select Mono units which sa sfy not only the total hea ng load requirements but also the total cooling load requirements.

4.2 Heat Pump Leaving Water Temperature (LWT) Selec on
The recommended design LWT ranges for different types of heat emi er are: § For floor hea ng: 30 to 35°C; § For fan coil units: 30 to 45°C; § For low temperature radiators: 40 to 50°C.
4.3 Op mizing System Design
To get the most comfort with the lowest energy consump on with heat pump, it is important to take account of the following considera ons:
§ Choose heat emi ers that allow the heat pump system to operate at as low a hot water temperature as possible whilst s ll providing sufficient hea ng.
§ Make sure the correct weather dependency curve is selected to match the installa on enviroment (building structure, climate) as well as ender user’s demands.
§ Connec ng room thermostats (field supplied) to the hydronic system helps prevent excessive space hea ng by stopping the outdoor unit and circulator pump when the room temperature is above the thermostat set point.

4.4 Selec on of the buffer tank and DHW tank

4.4.1 Selec on of the buffer tank
The heat pump must be connected to the buffer tank in order to sa sfy the minimum amount of water in the system. The volume of the buffer tank must be selected according to table 1-4.1.

n = number of heat pumps in cascade

4.4.2 Selec on of the DHW tank
The heat pump can be connected to the DHW tank. The tank can be with or without a built-in electric heater. The electric heater of the DHW tank must be installed below the tank temperature sensor. The tank temperature sensor must be above the heat exchangers in the tank. For the correct opera on of the DHW hea ng system with a heat pump, it is necessary to comply with the minimum requirements of the DHW tank given in table 1-4.2.
